' RAIL-JOINT.

- the fol owing is a specification.

tion wlth my improvements,

' of such squared neck y invention relates to rail joints.

The principal object of the invention is to provide a simple, economicaland eflicient rail joint.

Otier and further objects of the invention will appear from anexamination of the drawings and the following description and claim.

' The invention consists in the co. 1. l inations and detailshereinafter described and claimed. I

In the accompanying drawings-Figure l is a transverse sectionalelevationof a rail joint mechanism constructed in accordance with myimprovements; Fig. 2 a side elevathereof; and Fig. 3 a erspective viewof one of the squar d nec or shouldered olts.

In constructing a device in accordance I provide fish plates or angles ahaving erforations b theretln'ou'gh, which are ob ong or elongatedlongitudinally of the fish plates, such perforations having upper wallportions 0 and lower wall portions (1 extending in parallel relation.The rails e, to be joined, are rovided with erforations f, and bolts 9aving squared or shouldered neck or shank portions h forming shoulders,adapted to prevent the turning of the bolts, are inserted through theperforations in such angle irons and'extend throu 'h the perforations inthe rails. The square neck or shank portions of the bolts are,preferably, oblong in cross section, as shown being of such dimensionsthat the long sides portions engage the ulpper and lower walls,respectively ,of the e ongated perforations in the angle 1I0I1S or fishlates, so as to be held against rotation 'longitu there y, thuspreventing the loosening. of the nuts upon the bolts. The perforationsin the angle irons are of suflicient length to provide spaces on eachside of the bolt neck which permit the movement of the bolts sion andcontraction of changes in temperature.

To provide additional security against the the rails due toSpecification ot Lettersl'atent. Application filed September 80, 1905.

loosening of the nuts, nut locking members j are provided havingperforations through which the bolts extend, such locking members having11 per outwardly pro'ecting flange portions and lower outwar jectrngflange portions Z. The up er portions engage the upper sides 0 the nutsand the lower flange bottom flange ortions of the angle irons or fishplates, so t at such locking members are he] against rotation and areadapted to prevent the rotation of the nuts u n the bolts- Theperforations in the ockin members may also be elon ted longitudinally ofthe angle irons or h plates so as to permit the movement of thegitudinally with relation to either the fish plates or rails and thusprevent inj tightened, these flanges properly from the position shownmay be turned down in dotted lines in shown in full lines in said fiused in combination with ang plates having elongated pergor inglongitudinallyand with bolts having oblong neck portions gatedperforations, so as to be held t rotation, the rotation of the bolts an,1008- portions engage the.

all its advan- Fig.4 to the position 're, and when ations extendmountedin such" elonening of the nuts'thereon is eHBctHQHyPIQe vented.

By the above arrangement it will be seen that while the rotati looseningof the nuts is prevented, the angle irons or fish plates are effectuallyheld in position, and at the sametinie'an'efiicient means is providedfor permittin the relatlve movements between the rai s and. fish platesdue to expansion and contraction of the rails, whereby injury to theparts by rea sonof of the bolts and 1the joint mechlocked bolt Theperforations in 110 necks of the boltssuch expansion and contraptionvis" prevented, and an efliclent rail the ili reot i'on oi the" length ofsaid "fish plate;
